“…Thus, as shown by our results, the different methods of delivery for AAA anesthesia, TCI or MCI, may induce profound alterations to the hemodynamic state of patients. In previous studies, it is a common observation that patients undergoing TCI demonstrated better control of HR and blood pressure than patients receiving MCI [23,24], and it is an observation that the results concur with our current study. Furthermore, in our study, HR in the TCI-M and MCI-M groups only fluctuate slightly and both groups have minimal hemodynamic disturbances during the third phase (Figs.…”
